First question: The earliest recorded history of China is the Xia Dynasty in 2070 BC. In fact, the origin of civilization can be traced back to Yangshao culture 10 thousand years ago. Historical experts believe that China culture originated from the legendary era of Three Emperors and Five Emperors. The second question is that Chinese civilization has a long history and can be said to be the oldest country in the world, because other civilizations have been interrupted. The third problem is ancient Egypt: 1, pre-dynasty (stone-stone combination period, about 4500-3 BC100 BC) 2, early dynasty (1-2 BC, about 3 100-2680 BC) 3, ancient kingdom. The first middle period (7- 10 dynasty, about 2 18 1-2040 BC) 5. The Middle Kingdom Period (1 1-0) was about 2040 BC-1786) 6, and the Second Middle Kingdom Period (13- 17 Dynasty was about1786-/kloc). About 1567-65438+) Post-dynasty period (21-3/dynasty, about BC 1085-332) 9. Macedonian Greeks and Romans ruled from the beginning (332 BC-642 AD). Ancient Egypt should be the ancient India where the Roman Empire under Octavian perished: it probably originated in 2300 BC and ended in 750 AD. It did not die, but the ancient Indian civilization was replaced by Buddhist culture. It probably originated in 2200 BC, and in 539 BC, the Persians rose and Cyrus II attacked Babylon, which probably ended in this period.
